Hot Fill PET Bottles

Hot Fill PET Bottles

Normally PET bottles caused deformation when the temperature of the liquid over 65°C due to glass transition.

Thanks to the design contributions of our GM Mr Ma, Bange has developed the revolutionary multiple blowing stage and air cooling system two methods for hot fill (heat set) PET bottles. Both of systems are introduced to reduce the level of PET residual stress and increase the rate of PET crystallization. Now PET bottles can stand hot filling without any deformation at all.
